How Random Are You?

• This is pretty interesting. I've found it's fun to throw off the algorithm. Use your warmup to repeatedly guess the same number, and then don't use it for a while.

  I started just lagging the guesses of the machine, and it never seemed to catch on.

• What about the following strategy? You first think of a random integer n1 from 1 to 9, then you think of another one n2, perhaps one that you have not used very often, and finally say (n1+n2) mod 9 + 1. I think this strategy could make your selection more random . Perhaps someone could try it and report the results.

• Is anyone sufficiently paranoid that their first thought was, "Are you going to train a model on my voice?"

  (Yes, I saw the "type the numbers" option.)

• I know pi to 100 decimal places and so that was pretty easy to cheat it

• Rather than attempt to be random, knowing that I'm not, I wanted to see how well it can predict Math.random:

      setInterval(() => {
        const num = Math.round(Math.random() * 10);
        const ball = document.querySelector(`.typed-pad .ball-${num}`);
        if (ball) {
          ball.click();
        }
      }, 1000);
  

  This isn't very interesting, but it scratched an itch I had to see what would happen.

      The house's record
  
      The house called 18 of your 190 scored numbers: 9%.
  
      Blind guessing would average about 21.1 of them (11%).
  
      Only 1 of the 206 people in a psychology study was more random than you. The house found you extremely hard to read.
  

  I really want to know who was more random than a RNG

• This is a nice spin on the Aaronson oracle:

  > In a class I taught at Berkeley, I did an experiment where I wrote a simple little program that would let people type either “f” or “d” and would predict which key they were going to push next. It’s actually very easy to write a program that will make the right prediction about 70% of the time. Most people don’t really know how to type randomly. They’ll have too many alternations and so on. There will be all sorts of patterns, so you just have to build some sort of probabilistic model. Even a very crude one will do well. I couldn’t even beat my own program, knowing exactly how it worked. I challenged people to try this and the program was getting between 70% and 80% prediction rates. Then, we found one student that the program predicted exactly 50% of the time. We asked him what his secret was and he responded that he “just used his free will.”
